[gdal-dev] Raster to vector conversions....

Hello,

I am trying to find a method of converting a raster grid to a polygon 
vector that does NOT aggregate adjacent pixels that share the same Z 
value. In other words, I would like the output vector to be a grid of 
polygons where the number of polygons is equal to the number of pixels 
in the source raster file, and where the polygon attribute values 
reflect the pixel Z value. The script gdal_polygonize does not seem to 
be able to do this. Any other ideas on how this might be accomplished??

Thanks, Bill
